T 0 all whom it 'may concern:

Be it known that I, JESSE B. MARsHALL,'a citizen of the lnited States, residing at Medina, in the county of Medina and State of Ohio, have invented a new and useful (.rib Structure, of which the following is a specification.

My invention relates to sheet metal struclts object is to provide a strong, durable, ireproof and eoin} )aratively inexpensive crib adapted to secure more pei-lect ventilation and readiness of access, together with absolute freedom from dampness and from the invasion of rodents.

It consists mainly ol embedding in a cement or concrete base upon a suitable foun- (lation, a sheet metal bottom to which is therein secured a series ol` sheet metal plates, preferably perfo. ated throughout, solidly united at their respective contiguous longitudinal edges to form a crib chamber; said structure provided with a suitable cover, and a ventilator shalt extending into the chamber and having perforations to permit i'ree circulation of air within said chamber.

My invention is illustrated by the accom'- p'anying drawings in which- Figure l is a plan view of my metal crib with parts cut away toexhibit the interior. Fig. 2 is a vertical longitudinal section of same on the line X-Y. Fig. 3 is a detail view of the means I use to form the sheet metal joints in its present embodiment. Fig. 4, is a detail cross section of the lower part of one side of my crib structure, showing means of uniting the walls to the base and parts adjacent.

Referring to the drawings, 1 represents the vertical sheet metal plates, which being soldily united edgewise, constitute the body or chamber of the crib. I preferably unitel these adjacent longitudinal edges by con structing a flanged margin 10 on the same, and binding both flanges together by means ol' a superposed metal strip 11 bent in i'orm of a saddle, and secured by bolts or rivets a, as shown in Fig. 3. This superposed strip may however be omitted, or other means employed to securely unite said edges.

As the best means for covering the structure I form a sloping roof made u i by the solid junction of a seriesof triangu ar sheet metal platesl 2 which are secured together in the same manner above described, and may be of any desired slope or pitch. For the purpose of better ventilation, in corn cribs especially, I punch the several vertical sheet metal plates With numerous perforations as shown, and constructv a ventilator shaft 3, preferably also of sheet metal, and extend the same downwardly into and through the crib chamber, and secure it at its lower end solidly in the concrete foundation to give it stability, and perfor-a te it throughout its. entire length to adapt it to afford the freest possible ventilation of all parts of -the charnber, and means for drying the contents thereof, -which may thus be disposed all around said ventilator shaft..

A sub-foundation 6 for my crib lshould usually be constructed in a manner suited to the situation and character of the soil, but in general, it is suiiicient to lay acourse of loose stones or coarse gravel to a point below the frost line. Upon the foundationl construct a base 5 of concrete or cement, on which I 'first spread a thin layer to make the foundation level and even, and lay thereon a sheet metal bottom 7 to reinforce the concrete base, prevent dam ness from arisin within the crib, and allor means for attac ng the vertical Asheet metal plates 1 which rest thereon, and then add a la er of concrete several inches in thickness allrover this sheet metal bott-om, and extend the layer beyond the side plates (which are thus embedded therein at their lower ends) suliciently to form a neat base 5 all around the crib bottom as shown in Fig. 1. The lower edves of said vertical sheet metal plates may be solidly attached to said sheet inet-al bottom by means of bolts, anglo ironsor any other suitable fastenings suflicient for the purpose, the said junction being reinforced by the weight ofthe structure walls and the concrete environment aforesaid. This construction also gives solidity to the crib, and makes it water and dani i proof.

As a preferretlmeans for solidly uniting the lower edges of the walls 1, to the bottom sheet metal plate 7, I use a anged strip or angle iron c, and bolts (Z, locating lthe same either within or without the wall, and within the concrete layers 5 as shown in Fig. 4. I also provide a suitable openin(r 9, preferably in the roof, with a removable cover to facilitate the dumping of corn and other substances into the crib, and also construct a suitable door 4 at one side in front of an interior barrier in the usual well known Way to prevent free escape of the material within,A when the door is opened.

I am aware it is not new to construct av crib of perforated sheet metal sectlons and rovide Ventilating means therefor, and such do not-claim broadly.v My improvement lies in the novel method of constructing a concrete floor vfor suclr cribs, in combination with improved means for securing the Ventilator in position at the crib bottom, and the crib Walls to the concrete floor, simplifyingthe,v construction and strengthening its parts,

-and making the crib `more impervious to 'dem ness, and more enduring and 'impenetrab e, and other and diierent openings to the crib may be made if desired, but

therein, and a layer of concrete extending over said metal'plate beyond the-walls, said Walls being endwise secured by suitable fas-V temngs to sald metal plate; a base or margin of concretearound the bottom of said structure 1n connectlon With said floor, and a ven-A tilator depending through said crib and end- Wise-'secured insaid'floor, substantially as set forth and lfor the purpose specified.

2. In a crib structure, the combination with perforated sheet metal Walls, of a' concrete iioor, comprising a' sub-foundation overlaid with concrete, a sheet metal plate embedded therein, and a la er of lconcrete eX- tending over said metal p ate to said Walls, said- Walls being endwise secured by suitable fastenings to said metal plate and concrete a base or margin of concrete around the bottom of said structure in connection with said floor, and a ventilator shaft perforated from end to end, depending through said crib and endwise secured in said ioor, substantially as set forth andl for the purpose specified.

3. In a crib structure, the combination with a concrete floor comprising a-sub-foun- (lation overlaid with concrete, `a sheet metal plate embedded therein, and a layer of con-- crete' extending over said plate; of a series of solidly united and perforated sheet metal plates endwise secured by suitable fastenings to said embedded plate; a concrete base or margin connected tosaid floor around the bottom of said structure, and a perforated ventilator depending through said crib verti-I cally, and endwise secured in said floor, substantially as set forth.

In Witness whereof I hereunto set my hand.
